A Progressive Lens Simulator comprises an Eye Tracker, for tracking an eye axis direction to determine a gaze distance, an Off-Axis Progressive Lens Simulator, for generating an Off-Axis progressive lens simulation; and an Axial Power-Distance Simulator, for simulating a progressive lens power in the eye axis direction. The Progressive Lens Simulator can alternatively include an Integrated Progressive Lens Simulator, for creating a Comprehensive Progressive Lens Simulation. The Progressive Lens Simulator can be Head-mounted. A Guided Lens Design Exploration System for the Progressive Lens Simulator can include a Progressive Lens Simulator, a Feedback-Control Interface, and a Progressive Lens Design processor, to generate a modified progressive lens simulation for the patient after a guided modification of the progressive lens design. A Deep Learning Method for an Artificial Intelligence Engine can be used for a Progressive Lens Design Processor. Embodiments include a multi-station system of Progressive Lens Simulators and a Central Supervision Station.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A head-mounted Progressive Lens Simulator, comprising: an Eye Tracker, for tracking an eye axis direction to determine a gaze distance; and an Integrated Progressive Lens Simulator, for creating a Comprehensive Progressive Lens Simulation (PLS) according to a progressive lens design by simulating a progressive lens power in the eye axis direction, in combination with generating an Off-Axis progressive lens simulation (Off-Axis PLS); wherein the Eye Tracker and the Integrated Progressive Lens Simulator are implemented in a head-mounted display.
2. The Progressive Lens Simulator of claim 1 , comprising: a backlight; a first liquid crystal display, positioned in front of the backlight; a second liquid crystal display, spaced apart from the first liquid crystal display, for together simulating a progressive lens design by creating a light field effect; binocular viewing lenses; and driver electronics.
3. The Progressive Lens Simulator of claim 2 , wherein: the light field effect is one of three dimensional and four dimensional.
4. The Progressive Lens Simulator of claim 2 , comprising: at least one motion sensor, for sensing a motion of a wearer of the head-mounted display.
5. The Progressive Lens Simulator of claim 4 , the at least one motion sensor comprising: at least one of an accelerometer, a gyroscope, and a magnetometer.
6. The Progressive Lens Simulator of claim 1 , comprising: a backlight; a liquid crystal display, positioned in front of the backlight; a microlens array, spaced apart from the liquid crystal display, for together simulating a progressive lens design by creating a light field effect; binocular viewing lenses; and driver electronics.
7. The Progressive Lens Simulator of claim 6 , wherein: the light field effect is one of three dimensional and four dimensional.
8. The Progressive Lens Simulator of claim 6 , comprising: at least one motion sensor, for sensing a motion of a wearer of the head-mounted display.
9. The Progressive Lens Simulator of claim 1 , comprising: a housing, for accommodating the Eye Tracker and the Integrated Progressive Lens Simulator.
10. The Progressive Lens Simulator of claim 1 , comprising: augmented reality glasses, wherein the Comprehensive progressive lens simulation is generated from an image viewed via the augmented reality glasses.
